We’ve taken our whiskey taxonomy and quadruple-distilled it into a set of four perfect drinking glasses. Each 14 oz double old-fashioned tumbler breaks down a major variety of whiskey (Bourbon, Irish, Scotch, and Single Malt Scotch) into its constituent parts and variations. and makes the perfect gift for dram drinkers, snifter savants, and lovers at large of the ultimate amber elixir.
